Co_2 Reforming Of Ch_4 Over Co/oxidized Diamond Catalyst

摘要

We examined synthesis gas (H_2 and CO) production from CO_2 reforming of methane using a Co/oxidized diamond catalyst to investigate the properties of oxidized diamond as a support material and as a way to avoid carbon deposition on cobalt-loaded catalysts. Oxidized diamond showed a good catalytic performance among various support materials. No carbon deposition was observed when using the Co/oxidized diamond catalyst in CO_2 reforming of CH_4. In addition, CH_4 conversion was maintained for 10 h during CO_2 reforming of CH_4 over the Co/oxidized diamond catalyst. In the CO_2 reforming of CH_4, active cobalt species might be formed or deposited carbon would be rapidly eliminated on oxidized diamond-supported catalyst.
